VM.ERR

Description

Runtime errors are caused by the program running on the AKD BASIC trying to do something that is not allowed. For example, runtime errors occur when you attempt to write a value that is too high or too low to a particular variable. We try to catch as many errors as possible when the program is compiled, but some errors are only detected when the program is running.

Determine the particular problem causing Runtime Error (F4 Fault) by looking at the value of the VM.ERR variable. Use the Variables Window to find the value of VM.ERR.

The table below shows what each value of VM.ERR means.

Value of VM.ERR	Error Caused by:
801	Divide by zero.
802	Stack overflow.
803	Insufficient memory.
804	No interrupt handler defined.
805	Interrupt error.
806	Max string length exceeded.
807	String overflow.
808	Array out of bounds
809	Feature not supported.
810	Internal firmware/hardware error.
812	Parameter not supported.
813	Parameter access error.
814	Data not found.
815	Data invalid.
816	Data too high.
817	Data too low.
818	Param type out of range.
819	Data not divisible by 2.
820	Invalid position modulo setting.
821	Cannot read from command.
823	Enable Drive first.
824	DRV.OPMODE must be 2 (position).
825	DRV.CMDSOURCE must be 5 (program).
826	Cannot execute during a move.
827	Writing to read-only parameter.
828	Disable Drive first.
